Three rare types of Wilms' tumor were reported with collective review. Case 1, 6-year-old male with right lower abdominal mass was operated. A tennis ball sized tumor was found in place with no relation to the kidney. He developed metastases in both lungs 2 years 8 months after the operation. Those pulmonary lesions were removed. He has been in good health. He is now 14-year-old. Case 2, 9-month-old female, the first born of non-identical twins, was operated because of a fist sized left abdominal mass. The tumor involved the upper and lower portion of the kidney. Complete excision was successful. The NWTS stage was II. She had been well for 7 years after the operation. The second born also had Wilms' tumor which involved both kidneys. She who had not been operated, died 2 years after the diagnosis was made. Case 3, 1-year 7-month-old female was admitted with a tennis ball sized left abdominal mass. Abdominal aortography disclosed that the left kidney was involved but right was not. The tumor involved the lower pole of the left kidney which was removed completely. The middle portion of the right kidney was involved and only involved portion was removed. Histologically, both lesions were nephroblastic type of Wilms' tumor. Lymph nedes were not involved. She had been well for 4 years 6 months since the operation.
